我正在繪製3D對象,但繪製不正確。原始的3D文件沒有對角線,但是當我繪製時,它顯示對角線。請幫助我爲什麼繪製對角線。對象在openGl中不能正確繪製Es

在此先感謝。
我無法讓你100%。請幫我編輯我的代碼問題在哪裏。 – user2583144
它不在你的代碼中。發佈您的頂點數據。 – Tez
我已經將完整的代碼和obj文件上載到項目的資產文件夾中。請在這裏找到這個項目:https://www.dropbox.com/s/ejhlmgb86b05wv2/objLoader.rar ..請幫我畫一下正確的對象。對角線出現,物體內部出現許多扭曲。我無法識別自從最近4天以來問題出在哪裏..提升求助 – user2583144
